Of all the variations of poker, one is attracting plenty of attention just lately thanks to its popularity in the World Series of Poker and that’s Razz. Razz is a variation of Seven Card Stud poker that it’s played ace-five low. Here’s a basic outline of how it works.

In regular poker, hands are scored according to their rank, so that a royal flush is the strongest hand, running down through straights, pairs to the weakest hand called a High. Razz is played in the opposite direction with its strongest ranking hand, called the wheel, or bicycle which contains ace, two, three, four and five of any suit. Flushes and straights are not counted, so the hand’s strength goes only on its combination of numbered cards, not their suit. The next best hand is a high, meaning a hand that contains no pairs, which beats one with a pair. So a hand containing a pair beats one with two pair, which beats a three of a kind and so on.

In this game, there is no ace high, as ace is the lowest card, so the next best hand you can hold after a wheel is actually six high (six, four, three, two and ace) those being the lowest cards you can hold without making a straight.

Betting is much like Seven Card Stud, with an ante bet to get the game started and betting rounds from Third to Seventh Street. The holder of the lowest hand is the winner.
